9. Stray capacitance on antenna and board must be < 10 pF to achieve full tuning range at higher inductance levels.
1. The Si4736/37/38/39 divides the RCLK input by REFCLK_PRESCALE to obtain REFCLK. There are some RCLK
2. A frequency tolerance of ±50 ppm is required for FM seek/tune using 50 kHz channel spacing and WB tune.
